Instagram JDBC Driver

A straightforward interface to connect any Java application with Instagram integration capabilities including Users, Relationships, Media, Tags, and more!



Connect to Instagram data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Instagram data from a connection pool in Tomcat.

Connect to Instagram Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    Instagram uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with Instagram. See the help documentation for a guide.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Instagram JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.instagram.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/instagram" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.instagram.InstagramDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:instagram:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Instagram data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Instagram for all applications.

  3. Add a reference to the resource to the web.xml for the application. Instagram data JSP jdbc/Instagram javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/Instagram"); Connection conn = ds.getConnection();

The steps above show how to connect to Instagram data in a simple connection pooling scenario. For more use cases and information, see the JNDI Datasource How-To in the Tomcat documentation.
